CaribSea Aquatics BioMagnet Clarifier Aquarium Review

This solution is almost perfect for saltwater aquariums. Not only does it polarize the particles in the tank to bring them together and make filtration easier, but it also charges the filter media, allowing it to attract more particles during normal filtration. I've only seen good results from this when used either in a starter cycle or in installed tanks.

Used when I first set up my 29 gallon sand based tank to allow the sand to settle quickly. I think it helped for the first few weeks I used it. However, after opening it after a few months of not using it, it was filled with gray sludge (I didn't look closely - it was gross) and I didn't trust it enough to use it in my aquarium. Suitable for immediate use. but not in the long term.

I've used this a few times, I've learned to follow the directions on the bottle, use some water from the tank, pour the liquid into a mug in the water tank and then REALLY stir REALLY GOOD THEN add it to your tank. AFTER a water change I usually try to wait 24 hours to make sure my filters have done their job first! Balls all over the tank!
